COMBINATION SOLID AND VENTILATING DOOR- Specification of Letters Patent.

Patented Oct. 30, 1906,

To all whom it may concern:

Be it known that we, FRANK P. CLAIR and FRANK BASER, citizens of the United States, and residents of Archbold, in the county of Fulton and State of Ohio, have invented certain new and useful Improvements in Combination Solid and Ventilating Doors; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to doors of'the class adapted to be adjusted to form either a solid or ventilating closure for an opening, and is intended for use on barns, stables, cars, or other structures the doors or other openings of which it is desired at different times to tightlyclose, open wide, or partially open to form a ventilating-door," as circumstances may require.

The object of our invention is to provide a door of this class that is simple, cheap, and durable in its construction, easy of operation, and no thicker or heavier than the ordinary type of door used on structures of this class.

The invention is fully described in the following specification and shown in the accompanying drawings, in which Figure 1 is a partial elevation of a structure, showing our improved door as tightly closing an opening therein. Fig. 2 is a similar view with the door thrown open; Fig. 3, a similar view showing our invention adjusted to form a ventilating-door for the opening. Fig. 4 is a vertical cross-section of Fig. 1, and .Figs. 5 and 6 are details of two forms of joining the contiguous edges of the idndependently-movable bars or slats of the oor. 7

Referring to the drawings, A represents the side of a car, barn, stable, or like structure having a door or window opening B therein.

The door embodying our invention comprises the alternately-arranged laterallyabutting bars or slats a and a and the vertical end or spacing strips b and b, which are also alternately arranged and nailed or other wise secured to the ends of the bars or slats a and a, respectively, as shown, thusforming two independently-movable door-sectlons. The abutting edges of the bars or slats a and a are matched in tongue-and-groove or rabbeted fashion, as shown at c and d in Figs. 5 and 6, respectively, whereby the slats or bars of each section are permitted to have a longitudinal sliding engagement with those of the other section. Owing to the alternate arrangement of the said spacing-strips b and b, the degree of independent movement of a door-section is limited to the space intervening between the vertical spacing-strips of the other section.

A hanger-bracket e, which may be of any suitable construction, is secured to the upper end of each vertical strip 1) and b and is adapted to engage with and have a longitudinal movement on the horizontaltrack or strip f, which is secured to the side of the building above the opening B thereon. A strip 9 is also secured to the side of the building in position to engage the lower edge of the door and prevent a lateral swinging thereof. The sections of the door may be locked against independent movement by means of a slotted latch h on one of the strips 5 engaging a staple 'i on the contiguous strip 6, thus retaining the sections in either closed or open position.

j represents a handle on each of the doorsections, by means of which they may be moved. r

It will thus be apparent that the two doorsections may be positioned to tightly close an opening, as shown in Fig. 1, or onev moved longitudinally of the bars or slats of the other to form a ventilating-door having equidistantly-spaced openings, as shown in Fig. 3, or the two sections moved together to entirely uncover the opening, as shown in Fig. 2. The matching of the edges of the bars or slats of the two sections in the manner shown forms a close joint and prevents independent lateral movement of the two parts.

It will be noted that the side of each doorsection is of less surface extent or surface area than that part of the door-opening located within horizontal planes substantially coincident with the upper and lower edges of the door which acts to close the door-opening when said surface is in register with the opening or the extent of the solid surface which acts as a closing medium for the opening.

It will be understood that we have illustrated and described but a single exemplification of our invention; but the claims hereinafter presented will make it obvious that we are not to be limited to this particular species.

We claim 1. The combination with a structure having a door-opening therein, of a horizontallydisposed track secured to the wall of the structure adjacent the door-opening, and a door formed of two interfitting sections, each comprising horizontal, spaced slats and end bars each separately hung from said track and movable along the same, the slats of one section interfitting between the slats of the companion section:,. whereby both sections may be slid into a position over the dooropening, or both sections slid to occupy a po sltion to one side of said opening leaving the same unobstructed, or one section slid into a position to span the door-opening, and the other section slid into a position to one side of the door-opening, substantially as described.

2. A door comprising two sections formed of slats placed a distance apart with the slats of one section registering with the spaces of the other, said sections being movable relative to each other and in relation to the dooropening, in substantially the same horizontal plane or zone to an extent to bring both sections into position in which they span and close the door-opening or a second position removed from the opening or to a third position in which one section completely spans and partially closes the door-opening while the other section occupies a position entirely to one side of the door-opening.

In testimony whereof we have hereunto signed our names to this specification. in the presence of two subscribing witnesses.

FRANK BASER.
